Currently have a few vector lines that i want to create buffers for e.g. 10m, 20m,30m etc. I have created buffers but its not what i was aiming for, I want to see how another vector layer is affected. For more specifics I want to have a buffer region that goes from 0-10, 10-20, 20-30 etc but currently i have buffers that start from the original vector so its ending up as 0-10, 0-20, 0-30. Is it possible to create buffers for certain distances away from the interested vector or not? If so, how can I do this?
In QGIS 3.4.5 you can use
Multi-ring buffer (constant distance) in which you can specify the number of rings (in your case 3) and the distance is 10, if your projection supports meter unit, as you can see below:
You can find the tool from
Processing toolbox -> Vector geometry -> Multi-ring buffer (constant distance).
Here is the output:
and to make sure each buffer zone starts from the end of the previous buffer zone, I turned off zone 0-10 m:
